MUFFLER FOR EXPLOSION-ENGINES.

Specification of Letters Patent.

Application filed January 19, 1914. Serial No. 812,899.

To all whom z'tmay concern Be it known that I, CHARLES H. KENNEY, acitizen of the United States, and a resident of New London, in thecounty of New London and State of Connecticut, have invented certain newand useful Improvements in Mufflers for Explosion-Engines, of which thefollowing is a specification. This invention relates to that generalclass of mufllers in which a plurality of baflie plates are arrangedwithin a suitable housing, and my present purpose is to provide a novelconstruction and arrangement of baffle plates, whereby I am able todeflect, and check, the'exhaust gases resulting from the rapidlysucceeding explosions NVltllOllt objectionably retarding the passage ofsaid gases through the mufiier.

Briefly described, my said improvement consists in providing, within asuitable housing, a plurality of non-rotatable fan-shaped disks, thatare arranged in alternate right andleft-hand relation to each other and,by

preference, I pass through the said housing a current of water that isdischarged against the said disks in such manner as to separate thewater into-a spray that is carried forward by the exhaust gases until itsettles by gravity sufficiently to leave the housing by a special exitinstead of passing outward with said gases. The said water may thus beused in circulation and continuously.

In order to explain my invention clearly I have provided theaccompanying drawings, in which' Figure 1 is a central, longitudinal,sectiohal, view of a mufller embodying my presem improvements. view of arod upon which the baffle plates or disks may be strung and clamped andin Fig. 3 I have shown one of said plates. 7

Referring to these drawings, the letter a indicates an elongated,preferably cylindrical, shell which forms the housing or casing of mymuffler, the ends of said housing being adapted to receive an inlet pipe6 and an outlet pipe 0 for the intake and discharge respectively of theexhaust. Centrally located in the housing a is a rod d that is retainedin its central position and is pre vented from rotating, by a yoke ethat is fixedly boltedor screwed to the discharge end of the housing,the rod 03 being fastened to the yoke by means of a nut f. The other endof rod (1 is provided with a cone-shaped Fig. 2 ma detached' gases anddirects said gases against the initial bafile disk. The said baffledisks are strung on rod d, as here shown, and they are separated bywashers g, the disks being indicated by the reference letter k. Thediameter of the disks is slightly less than the interior diameter of thehousing a and said disks are formed as right-hand, and lefthand fansthat are mounted on rod d in alternate relation to each oother, as seenin Fig. l of the drawings, andso that the exhaust gases, in theirpassage through the housing, are deflected inltheir course as they passfrom disk to disk. Each of the Wings of the fans is also preferablyperforated, as at z' in order to more effectually break up and deflectthe volume of gas in its passage through the mufl'l r. By reason of therepeated impact of s hd g ses against the disks h, and their conse uentdeflection, the said gases are gradually checked and are finallydischarged through the outlet 0 in a spent condition.

In order to more effectually muffle the exhaustgases I preferablyintroduce into the intake end of housing a, (through a pipe is) a streamof water that strikes'the wings of the initial disk It at such an angleas to separate the particles of water into a spray which mingles withthe in-rushing gases and is carried forward by them until the force ofthe gases is somewhat spent, when the.

water drops by gravity to the lower side of the housing and passesoutward through a discharge opening m while the relatively lighter gasespass outward through .the discharge opening a, the spray of waterserving to CllSlllOIl and smother the gases and thus assist materiallyin muffling said gases.

My described device is so designed and constructed that its severalparts may be readily constructed and assembled and I find by actualdemonstration that it operates to overcome the objectionable noise whichresults when the exhaust is directed Z a gas inlet and an outlet inalinement with each other, a plurality of fan-shaped non-- rotatablebafile disks arranged in right and left hand relation to each otherWithin the said casing, meansextending longitudinally of the casing andsupporting said disks in predetermined relation, the end of said sup- 15porting means adjacent the inlet adapted to receive and deflect radiallythe inrushing gases, and means forintroducing water at the intake end ofthe casing and disposed at an angle to cause the Water to strike theini- 20 tial baffle disks.
